Williams Jet Tenders, the world’s foremost jet tender specialist, is proud to announce the approval of HVO100 fuel (hydrotreated vegetable oil) following successful first stage testing on selected DieselJet engines. This strategic move underscores Williams’ commitment to environmental sustainability and innovation in the marine industry.

Williams approves HVO100 for use on all its YANMAR 4JH engine powered tenders, including the DieselJet 415, 445, and 505, and SOLAS 505. Customers with these engines are encouraged to use HVO100 fuel to reduce their carbon footprint, as it can decrease emissions without impacting performance.

As a result, all new product developments and product testing powered by these diesel engines will utilise HVO100. In addition, Williams’ fleet of vehicles, including delivery vans and lorries, as well as the YANMAR 4LV powered models, are also looking to transition to HVO100 once further testing has been completed.

Sarah Moore, Sustainability Specialist at Williams Jet Tenders, commented: “We are committed to finding innovative sustainable solutions that reduce the direct emissions impact from our factory and our vehicles. By using UCO HVO, a renewable fuel made from waste cooking oil, we will accelerate our efforts to decarbonise. We hope that by using HVO in our fleet and in our approved test boats, we will raise awareness of the benefits of switching to alternative fuels. As we carry out exploratory testing on our products, it will allow us to confirm HVO use in more of our tenders, enabling us to achieve a greater reduction in our carbon footprint as more Williams Jet Tender engines are approved for use.”

The environmental sustainability benefits of UCO HVO fuels include reduced greenhouse gas emissions, utilising a renewable energy source as the fuels are made from waste cooking oil and help reduce dependency on fossil fuels. UCO HVO also produces fewer particulates, sulphur and nitrogen oxides compared to conventional diesel, reducing air pollution. Use of UCO HVO fuels also promotes better disposal of waste cooking oils. Overall, the use of UCO HVO fuels can significantly contribute to a cleaner, greener, and sustainable environment.

Floris Lettinga, Director of Sales and Marketing at YANMAR Marine International said, “YANMAR Marine International is proud to partner with Williams Tenders, a collaboration perfectly aligned to YANMAR’S commitment to sustainability. At YANMAR Marine International, we prioritise environmental responsibility, and this partnership highlights our ongoing dedication to our wider Green Challenge 2050. By integrating YANMAR’S HVO approved engines across the Williams Tenders’ range of boats and vehicles, we are not just propelling innovation; we are supporting our customers in propelling a sustainable journey towards cleaner future. Together, we help our customers navigate the steps towards optimising cutting-edge technology with environmental consciousness.”

This announcement is part of Williams’ broader commitment to sustainability, which has included several initiatives, including being awarded a grant by Innovate UK EDGE to test alternative, more sustainable composite materials and completing Life Cycle Analysis (LCA) for its TurboJet 325 and DieselJet 415 to calculate their carbon footprint. Williams Jet Tenders also hired a full-time sustainability specialist in 2023 and continues to follow its sustainability strategy which it launched in 2020, covering the need for action, with further sustainability updates set to be released in 2024.
